    ABSTRACT
    The orb-weaving spider Trichonephila clavata (L. Koch, 1878) (Araneae Nephilidae), commonly known as Joro spider, was recently introduced into North America and has been spreading in the invaded territory. Several studies have suggested potential negative impacts of this spider on native communities. The present study focused on risk-taking behavior in Joro spider individuals from their native range. A comparison between our behavioral experiment and a previous study investigating an exotic population in the USA suggests that spiders tend to exhibit more risk-aversive behavior in the introduced region. Although it remains unclear whether the observed difference is an adaptive or plastic change, knowledge on the adaptability of Joro spiders to novel conditions is crucial for assessing their impact on the ecosystem.

    Note on occurrence of the land slug family Rathouisiidae Heude, 1885 from South Korea and its DNA barcode
    https://doi.org/10.31396/Biodiv.Jour.2020.11.4.1015.1019

    ABSTRACT
    Rathouisiidae Heude, 1885 is a family of terrestrial slugs. Although only several species has so far been described in this family, rathouisiids are estimated to be highly diversified. In the present study, we report the presence of the slug of Rathouisiidae in South Korea and its DNA barcode for the first time.

    First record of the little-known land gastropod genus Nobuea Kuroda et Miyanaga, 1943 (Gastropoda Diplommatinidae) from Jeju Island, South Korea
    https://doi.org/10.31396/Biodiv.Jour.2020.11.1.289.292

    ABSTRACT
    Nobuea Kuroda et Miyanaga, 1943 (Gastropoda Cyclophoridae) is one of the least-known genera of terrestrial gastropods. An individual of this genus was collected from Jeju Island, South Korea, the first record of Nobuea from this island. Further studies are needed to investigate the taxonomic and conservation status of the Jeju Nobuea reported here.
